:of which the following is a specilication.

My invention relates especially to ribbon mechanisms for typewritingmachines, and its object generally stated is to rovide improved devicesof the class spec 'ed.

` To the above and other ends, the invention consists in the features ofconstruction, combinations of devices and arrangements arts hereinafterdescribed and particular y` pointed out in the claims.

My invention is shown as applied to a 4front-strike typewriting machineof the shifting platen style or type, but the nature of the 4inventionis such that it may be adapted to.

other kinds of writing machines;

One form of the invention is illustrated in the accompanying drawings,wherein- Figure 1 is a vertical front to rear sectional view` of a.typewritng machine embodying 'my invention, said view being taken aboutcentrally of the machine, various parts ol' Fig. 2 is a sectional viewtaken on theI plane represented by. the dottcd line x in Fig. 1 andlooking in thc directionol" the arrow at Said line, parts ot' themachine boing broken away and parts and showing dctails ol the ribbonmechanism, certain ol' tho ports boing` in d'illcrcut relations fromthose in which theirr appear in Fig. l.

A roller 2:12 mounted at the front of the har 3Ucor'iperates with a shiftablc guide rail c.; which is supported. nearits ends on upright rods 34 movable through open.- ings in tl-.e topplate. said rods being fixed to ani..v ""izing from a cross bar 35.,Said cross bar in turn is carried by vertical rodsS each pivotallyconnected at 37'with a shift lever 3S pivoted on a. rock shaft 29intermei'liate its ends and termina-tin g at the-front of the machine ina key button 40. During the travel of the' carrie. e back and forthacross the top plate the re ation of the .lateii 8 and platenrarrierwith said carriage will orl'linarily remain. unaltered, theroller 33 beck and forth over the shift rail 33. Wer, it be desired toprint in upper case, one of the shift keys 40 may be depressed, thusraising the shift frame comprising the rods 36, cross bar 35, rods 34and shift rail 3?, and thereby raising the platen carrier andplaten toupper case position.

. Stops 35 and 35h 4operate to limit the shifting movements of thcplaten. Except for the;connection between the crank arm ,'32 and theescapement devices (said connection. comprising the bell crank 17, its.support and, the links connected with said bell (rank), the parte, abovedescribed are not original with. me and are not claimed herein, save incombination with other devices presently to be described.

.f1 ribbon 41 is secured to and wound upon ribbon spools 42l saidribbon` spools being vertically disposed beneath the topplate, one ateach side of the machine and forward ofthe platen as shown in Fi s. 1and 2. Each ribbon spool is secured-to t e forward end of a horizontalshaft 48 journaled4 in lugs depending-from the top plate. Referring tothe diagrammatic. lan view (Fig. 13) it will be seen that the s raft 43is provided at it's rear cnd witha bexeled pinion 44 which is adapted tocooperate with avbeveled drix ing pinifiin 45 secured to a drii ing orpower shaft 46, the latter being connected with and adapted to receivemotion from the spring drum. 15 through a train of de: ices comprisingbei eled pinions 47 ande-8, said inions'being constantly in mesh witheac other. The pinion 48 issuitabl connected with the spring or theother of the driwinpinions 45 with its y causing the assoribbon thereon.

ciate ribbon spool to be turned to wind the Any of the known or suitable means may be employed to connect the shaft 46 with the pinion 47 tocause the latter to turn. said shaft while at the same time perlnittingindependent endwise Inovenent ofsaid shaft. Midway between the ribbonspools the ribbon 41 is threaded through a vlbratory carrier or vibratorcomprising'a body portion 49 75 and two lateral hook-like extensions 5()which cooperate with the body portion to. prov-ide slots through whichthe ribbon passes in such a way that the printing portion thereof, orthat portion between theslots, is maintained sf in a v ertical orsubstantially vert-ical position and extends lengthwise of the platen.-The vibrator is guided and supported on the upright arms of a. bracket51 which is secured to the top plate of the machine by screws 51". 85The 'lower end of the Stein 49a of the vibratory carrier is bifurcatedand carries a cross pin 52 which pivotallyengagesv with :in operatinglever, -which .in the present instance com rises two parts jointedktogether and ca- Yrised. in therear' part of 'the'operating lever. 10`0h'e parts of the operating lever are pivotallyv connected or jointed. at57, so 4that relative n'rovernent between the two parts may be had. 1nthe present' instance relative movenient is obtained by swinging thepart 53 on 105 the pi,;'ot^ .57 during platen shifting move ments byIneens presently to he described` and for purposes hereinafterexplained. Besides the member 56, the rear part of the operating leverpreferably further comprises a 11 member 58, the forward end whereoffits into a slot or'lrerf in the rear of the-rnen'iber 56, f -the twonienibers-56 and 58 bcingsecured togethcr by means of rivets 59 or 1n.any other` suitable way. 'The member 58 is formed ot 115 thinner stockthan thc member' 56 as shown in Fig. 4 but said member 5S, viewedfromthe. side as in Figi 3, is considerably wider than the member 56'.-lt will ofcourse be apparent that instead of being-composed of two 1.20

incmbers the rear part of the operating lever may consist of one memberwhich may be made in the desired shape or form and that the two parts ofthe operatinfr lever instead of besaine plane ass own may be -in dif-125 tiel plan A '"b ber 58 i. le ceifed in a slot in a bracket or 60depending from Atheto-p plate andis pnroted. on

ashouldered screw 61 which passes through said lug from. side tojsideand serves as a fulthe head thereof pro'ects beyond t e face of the lng60 and is re uced as indicated at 62 (Fig. 4) for a'purpose presently tobe explained.

The rear portion of the member 58 behind the fulcruni 6], is formed witha slot 63 which receives a cross pin 64 (Figs. 1 and 2)'carried at thetop of arms 65, saidarms beingfornied byliifurcating the upper and widerportion of an actuating link, the stem. 66 Whereof'is pivotallyconnected at 67 with the horizontal arm of the bell crank lever 17. Thesl'ot 63 is arcuate beingr struck from' the pivotal point 67 of theactuating link as a center so that the pin or actuating device 64,carried at the upper end of said link, may when the link is swungloligitudinally of the operating lever, pass freely from one end of theslot 63 to the other. The )in 64 is constantly urged toward the rearend/of the slot 63 b adraw spring 687 one end of which is secui d to thestem 66 of the actuating link and the other endto an arni 69 fixed toand extending vertically upward from the rearend portion of the arm 19.

-' The position of the pin in the slot is deter- .mined by a'positioningmember which coperates with the forked or bifurcated up'per portion ofthe actuating link. Said member is clearly shown in Figs. 1V and 2.`nounted on the ribbon driving shaft 46 and comprises a circulardisk-like pai't or face 70 concentric with the shaft 46, a secondooncentric disk-like part or face V71 of lesser diameter andl aneccentric disk-like )art or face 72, the reatest radius wliereocorresponds with t e radius of the disk 7 0 while its least radiuscorresponds with the radius of the disk 714 The disk 71 is between the Ydisk 7( and the disk 72 and is connected therewith by .coned or caniparts or faces numbered respectively 73 and 74;r The controlling memberis grooved to receive a feather or spline 46a which is fixed to theshaft 46 and connects said shaft and member so that thelatter is forcedalways to rotate with the shaft but may be slid lengthwise thereon so asto bring one or another of the disks 70, 71 and 72 into co'iperationwith the actuating link. To provide for this sliding movement of theeontrollin member on the shaft said member is provided with an extensionor collar 75 which is formed with'a circumferential groove 76, thelatter coperating with the forked upper end portion of an arm 77. Saidarm forms part of a handolerated means and'has a hub portion 7S w iichis fixed to the inner end of a slide rod 79, that is supported on aninverted T- shaped bracket depending front the top plate. The outeror-right-hand vend of the rod 79 carries a collar 81 in which'is fixed aforwardly projecting-horizontal p in 82.

It is Said pin engages in an elongated slot S3 bears in ythe right-handfront corner post and Y has fixed toits forward end an upwardlyextending crank arm 87 provided with a handle or finger piece 88 bywhich the crank arm 87 may be turned .to give oscillatorv movement tothe rock shaft S5, slide the rodv79 back and forth and move thecontrolling member transversely of .the actuating ,lirikm Any othersuitable means for moving the controlling member on the shaft 46 may beein- `ployed. -Any suitable means maybe provided to retain the handoperated means in one or another of a plurality of 'positions so as' tomaintain the controlling member in redeterinined relations with ltheactuating ink. For exam ile, the crank arin S7 may be provided witlh arearwardly extending pointed lug 87 which may engage with om` or anotherof three holes 89 formed in the corner post,the crank arm beingsulliciently resilient to permit the withdrawal of the lug fromengagement with one 1101089 so that the arm 87 epd the paitsconneetedtherewith may be moved until said lug engages with another one of theholes. Suitable indicating marks as N, B and R may he provided on thecorner post above the holes 89, and the crank arni 87 may be providedwith a coperat'ing pointer 90.

The arts are so arranged and proportioned t at when the pointer 90 isopposite the mark N meanin normal, the eccen- =itric'disk 72 of thecontro ling member will be distances from the fulcruni thereof when thcQ printing keys are actuated. At such operation of the )rinting keys itmii he understood that t e actuating link will he drawn downward,pulling down the rear arm of the ythrown will be progressively varied,causing like 41 it is usual] the types to folllow a/path extendinglengthwise of the ribbon and curving or waving back and forth from oneedge thereof. to the other.

From a consideration'of Fig. 1 it will be apparent that the eccentricdiskf72 and the concentric disk70 are arranged quite Iclose to the rearendportion of the operating lever.

Y vIn order to .enable said lever to be vibrated without beingobstructed by the disks 7 2 and 70 when they are Vin operative'position,said disks are respectively formed with ycircumlferential grooves ordepressions numbered respectively 72A and 70 thus providing openingsthrough' 'which the end of the operating sired be employedwith a ribbonsuch as that 1e drawings and numbered 41,

shown in' t which ribbon is divided into two longitudiv` nal stripes orfields-,marked a and b, of differlent characteristics. These stri es forexample may be different infcolor, t e field a being, say, black and thefield b, red. Instead of 'employing thecross'feed with a ribbondesiredhowever to make use exclusively o one field or the other atpleasure, and the controlling meinberand associate devices provide meansfor: enabling this result to be accomplished.v When, for example, it isdesired to make use of the 'black'fiehh the handle .88 is operated toposition the pointer 9() o posite the indicating mark B, causing t 1ehand operated-devices to act on the controlling member so as to slidethe lat-ter on the shalt 46 until the l'ace 71 vin engagement with theactuating lilik y which will be drawn by its spring 68` rearward,Icausing the pin 64 to operate at the rear o'f the slot 6,3 the normalposition ol' the parts at this time bing'indicated in Figs. 1 and 2. Theactuation ol' the printing keys when the parts' are so positioned willoperate to give the ribbon carrier its least extent ol' vibratory throwand will bring the upper or black lield (i opposite" the printing point.v As .long the concentric face 171 v remains operative the throw ol' thevibrator will be a coni stant one and the typesiwill 'l'ollow' astraight path lengthwise of the vfield ai. i

In the presentconstructionv it will'be recalled that the platen isshifted for change of ease and it W1 l further be noted. that the ribbono erating lever has a iixedand uncrum. f In order to compensate forenablin t 'e ribbon carrier to be shifted automatica y when the laten isshifted, this being accomplished by. reaking the hinge- `l1ke' or lockJoint between the two parts of the operating lever or more specificallyin 1 the (presentfinstance, by swinging the for- War part {13cm-the,pivot connecting it with shifting of the platenand the movexne'n' if Fle means ein loyed inthe prcsent'instance for breakingt e joint andswinging the ait 53 on the pivot 57, is shown clearly in Bland 4, andcom rises a pin or lug 91 fixed to the arm 53 a `ove* the pivot 57 andeX- This pin enters a hole or opening AformedA in :in extension or li 92curving upward and forward from. a bibck-like meinberor slide 93. Saidblocklike'inember is slidably mounted on the arm or member 56 and. iscontrolled by a connectingm'ember or connection 94 horizontally disposedand pivoted at its forward end on a shouldered screw 95 ixed to theslide .93. The inner face' of' the 'rear end of said connection 94 isformed with a longitudi- 'nally extending depression 96 which coperateswith the .reduced end (S2 oi the screw 61, said end 62 serving to guideand su port the said connection at its rear. dered screw 97 is securedat the rear end o f said connection, and-the shouldered or barrelportion of saidfscrew QTCOperat-es with a cam slot 98 formedA at theupper or angled portion of a rigid arm 99, said arminclii'iing upwardand rearwardl from the cross rod 35 and being provided with acollai"po1'ti in 100 which {it-s over the rod 35 and is iixcdly securedthereto by a set screw 101. The

igs. 1,l

the rear part `of the o erating lever, said Y 4rear part remainingunisturbed during the A. s oullower .case position of the arm or member99. is shown in Fig-1, froin an' inspection whereof it will benoted thatthe upper end of the slot 98 is at lthis time in cooperation -with thescrew or proJection 97 on the connection`94 and that the slot 98inclines downward and slightly .rearward from said screw 97.` When oneof theY platen shift-ing keys 4() is depressed to`V raise the platenshifting frame andthe `platen it will o rate to raise .portion of thescrew 97, forcing the latter towards the rear and causing the connection94 to move longltudlnally rearward, the

screw end 62 cooperating with the depres.

sion 96 to guide said connection. The rearward movement of theconnection will operate to slide the block-like member or slide l 93rearward on the member 56, causing the extension 92 to pull against thelug 91 andl swing the forward lever part 53 upward on the plvot 57. ittheribbon carrier and t e printing portion of the ribbon so that therelation of the latter with the platen when the latter has reached uppercase i )osition will be the same as its relation with t e platen whenthe latter was in the lower case position. 4

Instead of pivotally mounting'the connection 94 on the slide, 93, saidconnection may be rigidly secured to the slide.y In Fig. 15 l have showna modified construction inl which the slide 93 1s provided with aninte,-

gral or rigid extension or connection 93a carrying the screw 97. Ifpreferred the modilied construction of Fig.V 15 may replace thecorresponding construction sho'wn in the other figures. Of course if themodified construction is employed no guide is needed for the rear end ofthe connection 93". i

'lhe train of devices comprising the pin 91, slide 93, connection 94,screw 97 and arm 99 not only operates as a shifting means .to vary therelation between the two parts of the op-I erating lever, but alsooperates to lock or mantainsaid parts in either of the two relationswhich they bear to one another during' vibratory printing movements, oneof these relations being shown in Fig. 1 and the other in Fig. 3. ltwill be' noted that when the parts are .related as in Fig. 1 the screw97 is' co-axial with the fulcrum of the ,operating lever, so that therewill be no bodily movement of saidscrew during vibrator-y movements ofsaid. lever, but said screw will simply rotate 'on its own axis. Thenthe parts have been shifted to the positions shown inFig. 3 the screw 97having been moved backward away from the Lente" of rotation will have a'slight bodily movement about vsaid center during vibratory movements ofthe operating lever. 'To permit of this bodily 'movement the slot 98 hasan extension below the screw 97 and arcuate in shape, the arc beingstruck from the center vof rotation of the operating lever so that saidscrew may rotate slightl about said center without lnterfering with t ep'roper operation of the parts during their vibratory movements andwithout al.

tering that relation between the two arms of the operating lever showninFig. 3.

Said lever art will carry with Figs. 5-12 inclusive.

, During the reshifting platen from up er to ower case the rear edge orwall o the slot 98 will operate movement of the against the screw 97 toforce the connection 94 and slide 93 forward,- said slidemovin alongthevarm 56 and the extension92 o said vslide operating on the lug l91 toswingl consequently the relation between the slot.63

and the coopera-ting pin 64 will not be altered or-disturbed in anyrespect. Consequently .the vibratory movements imparted to the operatinglever by the actuating link 65-66 will be the saine in extent after theshift of the platen as before. the shift, although of course the,starting and stopping ositionsof the vibratolry ribbon carrier and t eprintin portion of the ribbon will be altered by sai shift by reason ofthe pivotal movement of the arm 53 on the center 57'. 1 These facts willperhaps be more clearly apparent after a consideration of thediagrammatic views, Fig. 5 illustrates the normal relation between theplaten a'nd the printing portion of the 'ribbon when the platen is inlower ca'se position. Fig, 6 illustrates' the printin r vposition of theribbon when the upper ha .fof it is being used, or, in other words, whenthe pin 64 is at the rear of the slot 63, as illustrated in Figfl. Fig.7 illustrates the normal relation between the platen and theprintingIportion of the ribbon after the platen has been shifted, while Fig. S

shows the printing relation between the platen and the ribbon when thelatter is in shifted positionand the upperghalf of the ribbon is beingemployed. Comparing Figs.

5 and 7 it will be noted that the relation between the platen and. theprinting portion of the ribbon is the same in both, although theirabsolute positions have been varied. This last statement also applies toFigs. 6 and 8. Figs. 9-12 correspond respectively to Figs. 5-S` but withthe lower half o f the ribbon in use instead of the u per half. Fig. l

9 shows the normal relation o the platen and ribbon in lower caseposition. Fig. 1() shows the printing relation of the platen in lowercase osition and the ribbon when its lower half 1s being employed. Fig.11 shows the normal relation of the platen and ribbon in uppercase'position, while Fig. 12 shows the printing relation between theplaten, in ulp- )er case position and the ribbon when t e lower halfthereof isv being employed. It will be noted that Figs. 9 and 11 showthe same relation between the printing portion of the ribbon and theplaten and that Figs. 10 and 12 show the same relation between theplatenV and the printing portion of .the ribbon. but

yeruin being non-shiftab samenormal-l -tions of the p the latterrelation of. course difers from the -rstj relation. It will further benoted that the relation between the platen and' the -nrintingportion ofthe ribbon is the same 'in igs. 5, 7, 9 and 11. In other words, the nor--rnalrelation between the platen and the ribbon is` an unvarying one nomatter whether theplaten is iii upper or 1n vlower ease Vor lwith theplaten; that the ribbon earrer'is -vibrated at printing operations by anoperating lever which has a singlle fiilcruni, said fulposition for boththe Shift aten; that said operating is in the presentinstaneemadeinparts, the 4forward part of said lever, bylwhieh is meant thatpart of the lever nearest to the vibrator,
